Tree Diversity

Emerald Ash Borer (EAB) was found last year in Boulder, Colorado.  EAB is new for Colorado although we have been expecting it for quite some time.  A group of tree loving professionals assembled a panel of fantastic speakers for talks on tree diversity hosted by Denver University.  Steve Bieberich, a very humble and knowledgeable nurseryman and owner of Sunshine Nursery, was among the presenters.  This was a great opportunity to hear about some of the newer varieties of trees, or unusual ones, and hear how they perform and grow.  Steve has helped introduce some great varieties, one in particular that Loma Vista is now growing is the Schmidt introduction Ulmus propinqua 'JFS-Bieberich', aka Emerald Sunshine. 
This is a beautiful vase shaped elm.  It does not get nearly as tall as its counterpart, Ulmus americana, growing only to a width of 25' and 35' tall.  It is resistant to the elm leaf beetle and is disease tolerant of Dutch Elm disease and phloem necrosis.  This is a great one to add to the list for Green Ash replacements and help diversify our tree palette!   

What other trees are you using to replace Ash trees and help diversify our urban forests?
